Hyundai Genesis (DH): Air Conditioning System / Photo Sensor Description and Operation

Description
The photo sensor is located in the right side of the inside rearview mirror.
he integrated rain sensor is located in the right side of the inside rearview mirror. The integrated rain sensor is a multifunctional sensor which combines the photo sensor and auto light sensor, and has a built-in photovoltaic diode (for detecting the amount of solar radiation). The electromotive force, which is generated in proportion to the detected radiation quantity, is transferred to the automatic temperature control module to compensate air flow and discharge temperature in the air conditioning system.

    Inspection 1. Turn the ignition switch ON. 2. Blow warm air into the in-car sensor air inlet. Measure the sensor resistance between 1 and 3 terminals.

    Inspection 1. Turn the ignition switch ON. 2. Connect the GDS. 3. Emit intensive light toward the photo sensor using a lamp, and check the output voltage change.
